To Reproduce

asdf list all php

Describe the Bug

When typing this command below:

asdf list all php

I receive the error:

Plugin php's list-all callback script failed with output:
awk: line 1: regular expression compile failed (bad interval expression)
({})

This is a crystal clean Ubuntu 23.10 installation.

Expected Behaviour

List all latest PHP versions, eg:

...
8.3.0beta1
8.3.0beta2
8.3.0beta3
8.3.1RC1-clean
8.3.1
8.3.1RC1
8.3.1RC2
8.3.1RC3
...

I just found how to fix the issue. It seems that in Ubuntu 23.10 version it's using 'mawk' instead of 'gawk'. The easy and quick fix would be just installing 'gawk' with the command below:

sudo apt install -y gawk

I don't know how this impact the whole system, but you can still switch easily between awk versions with the update-altenatives command, eg:

update-alternatives --config awk

Still, a possible fix for this would be

diff --git a/bin/list-all b/bin/list-all
